I’ll prepare three predefined themes for you as we discussed:

1. First theme: A light blue (very bright) for bullish candles and a light pink (very bright) for bearish candles.
2. Second theme: Neutral tones, using gray for bullish candles and white for bearish candles.
3. Third theme: Something more unique and contrasting, like neon green for bullish candles and bright orange for bearish candles.
